How is snap freezing tissue used in research to preserve cellular structures and biomolecules for future analysis?
Snap freezing tissue is a method used in research to quickly freeze samples at very low temperatures, preserving cellular structures and biomolecules. This helps prevent degradation and allows for future analysis of the tissue without compromising its integrity.
What is Wright's stain?
A chemical used to stain tissue samples for laboratory analysis.
What is an unfixed tissue?
Unfixed tissue refers to biological samples that have not been treated with a fixative to preserve their cellular structure. Unfixed tissue is more prone to degradation and changes over time compared to fixed tissue. It is typically used for special analyses or research purposes that require fresh tissue samples.
For what are FFPE samples used for?
FFPE human tissue samples are used in medical and scientific research, especially histopathology, as they allow pathologists to diagnose diseases and identify abnormal cellular structures. FFPE samples are also used in immunohistochemistry and in situ hybridization techniques to detect biomarkers, gene expression patterns and to locate proteins. They are also used for genomic studies, transcriptomics analysis and proteomics research. FFPE tissue samples play an important role in drug development, personalized medicine, and biomarker discovery. We offer human tissue samples on our website and gathered more information and FAQs there, feel free to dive deeper in the topic: centralbiohub.de/biospecimens/cancer-samples/ffpe-samples
Can liquid nitrogen be used for snap freezing?
Yes, liquid nitrogen can be used for snap freezing biological samples. When samples are immersed in liquid nitrogen, the rapid freezing process helps to preserve the integrity of the cells by preventing the formation of ice crystals that can damage the cell structure.
What are some methods of preservation?
Food preservation involves preventing bacteria growth using methods that include freezing. Canning, pickling, dry salting, fermenting, and drying are other methods of preservation used for food items.
Where in the world is food preservation being used the most?
Every culture in the world uses some type of food preservation. Types of food preservation include: freezing, dehydrating, curing, smoking, fermenting, and canning. It is not possible to estimate where these methods are being used the most.
What are common method of food preservation?
Freezing is a very common method of food preservation. Canning is another method that is often used. You can also dry, or vacuum seal foods to preserve them.

Why is nitrocellulose used in tissue printing?
Nitrocellulose is used in tissue printing because of its high binding capacity for proteins and nucleic acids. It allows for the efficient capture and immobilization of biomolecules, enabling the transfer of tissue samples onto membranes for analysis. Additionally, nitrocellulose provides a stable platform for detecting specific target molecules in biological samples.
What modern methods were used for food preservation?
-vacuum packing -heating -freezing -cooling -boiling -waxing -smoking -drying -bottling and canning -
Can i find information on supercooling?
Supercooling is the process of cooling a liquid below its freezing point without it solidifying. It is often observed in pure liquids or liquids with impurities. This phenomenon is used in various industries, such as in the production of supercooled water for cloud seeding or in the preservation of biological samples at ultra-low temperatures.
